While screens for the foregoing purpose are well known, they are generally subject to certain disadvantages, such as rattling by the wind, accidental and mischevious displacement by children, due to adjustment from the inner side of the window, and smooth operation when adjusting and removin from the window.

Having these matters in mind, it has been an Object of the present invention to provide a two part screen adjustable to any ordinary window below the sash and which is positively anti-rattling when adjusted.

A further feature is the provision of a positive locking means, inaccessible from the inner side of the window, but readily adjusted upon raising the sash.

Another aim is to produce an inexpensive screen; easily applied or removed, and which is entirely free from rattling when properly adjusted.

These several advantageous objects are accomplished by the novel construction, combination and arrangement of few and simple parts as hereinafter described and illustrated in the accompanying drawings, constituting an important part of this disclosure, and in which:

Fig. 1 is a front elevational view of a con ventional type of window, showing an application of an embodiment of the invention, looking from the outer side thereof.
